4 Claims. (01. 292-58) The present invention relates to certain new anduseful improvementsin fastening means for double-hung relativelyslidable window sashes and has more particular reference to means whichis characterized by a keeper carried by'the upper sash and a retainingbolt which coacts therewith and which is carried by the lower sash.

These types of sash fasteners are aptly and satisfactorily used in thetrade for burglar-proofing window constructions and are also notable inthat they function as reliable anti-rattlers. The object of the instantadaptation is tostructurally, functionally and otherwise improve uponsimilarly constructed and performing prior art bolt-type fasteners.

Another object of the invention is to bring into use a fastener in thestated line of endeavor which, because of certain unique features whichare embodied therein, will prove to meet ordinary requirements and needsof manufacturers and users alike.

Briefly summarized, the invention has to do with a retaining bolt, anovel bracket by means of which the bolt is stationed for use on anupper corner portion of the lower sash, keeper means for reception ofthe coacting end of the bolt, said keeper means being carried by theupper sash. In addition, there is a practical brace and this takes theform of a relatively movable bracket, the same serving to stabilize theintermediate portion of said bolt.

Other objects and advantages will become more readily apparent from thefollowing description and the accompanying sheet of illustrativedrawings.

In the accompanying drawings, wherein like numerals are employed todesignate like parts throughout the views:

Figure 1 is a fragmentary perspective view illustrating a window frameand double-hung upper and lower sliding sashes therein and showing, whatis most important, the sash fastening means constituting the subjectmatter of the instant invention.

Figure 2 is a view in section and elevation which may be said to betaken approximately on the vertical line 22 of Figure 1, looking in thedirection of the arrows.

Figure 3 is a view like Figure 2 but showing the retaining bolt in itsopen or released position.

Figure 4 is a fragmentary perspective view of a modified keeper for thestated bolt.

Figure 5 is a fragmentary perspective wherein the form of the inventiondepicted in Figure 4 is slightly modified in order that it may be fas- 2tened on the sash frame in a slightly different manner.

Reference is had to Figures 1 to 3, inclusive. In Figure 1 the windowframe, as an overall structure, is denoted by the numeral 6 while thelower slidingsashis denoted at 8 and the upper sliding sash at H]. Theseare, of course, conventional parts of a window. The sash ill, in orderto accommodate the present invention, is formed in one of its verticalrails, adjacent the lower lefthand corner, with a recess or mortisewhich is provided with keeper means. The keeper means in this instanceis a simple metal or equivalent cup 12 which is fitted into the mortiseand which functions as a socket member.

The stated bolt is denoted by the numeral [4 and this comprises asuitably threaded stem or shank 16 having a smooth terminal end I8constituting a detent, the latter fitting telescopically and removablyinto the keeper socket or member. There is a stop flange 2D dividing thedetent from the threaded portion of the shank. This flange is of alarger diameter than the socket member and not only abuts the sash butcovers the socket member and provides a satisfactory association ofelements. The left-hand end portion of the bolt is provided with asuitable finger-grip 22.

The bracket which mounts the bolt is a simple device and is denoted bythe numeral 24. It comprises a post-like upright 26 having projectingbase forming lugs 2828 atits bottom. This upright is preferablyrectangular in cross-section and has a screw-threaded passage extendingtherethrough which thus transforms the upper end of said upright intowhat may be called a nut for the bolt. It will be noticed that the baseis provided with a central depending screw-threaded portion whichconstitutes an anchoring screw 30 and this is, more specifically, a woodscrew. Thus, the bracket is simply screwed into place at the desiredpoint in order that the detent on the bolt will line-up with the keepersocket on the upper sash, as shown best in figure.

In order to relieve the bolt of shearing strain and to stabilize theoperation of the same and to insure longer lasting alignment between thebolt and socket member, a brace is provided and this takes the form of arelatively movable bracket 32 which, in many ways, resembles the bracket24. Here again, an upright 34 is provided and this has projecting baseelements or lugs 3-5 and there is a hole 38 through the upper endportion which lines up with the aforementioned nut. The hole 38,however, is smooth and of a diameter larger than the outside diameter ofthe bolt.

Hence, the bracket or brace 32 is freely slidable in relation to thebolt and vice versa. It is undesirable, it is believed, to actuallyfasten this bracing bracket 32 to the sash. Therefore, it is free ofattachment and may be slid to assume the best usable bracing positionwhich is usually that shown in Figures 1 and 2. There may be instance,however, when it is desired to retract the bolt to the extent shown inFigure 3 and in this situation the flange 20 engages the bracket 32 anddrags same toward the fixed bracket 24. Thus, there are spaced parallelperpendicular brackets, one of which is fixed as at 24 and the other onebeing slidable, this being the bracket 32. These two brackets coactingwith the simple bolt provide an unusually satisfactory and reliableassemblage of parts.

If one does not desire to use the keeper socket l2, he may dispense withthe same and employ, in lieu thereof the type of keeper means shown inFigure 4. The latter means comprises a fixture which is denoted at 49and which takes the form of an attaching plate 42 secured by fasteningscrews or the like 44 to the rail of the sash Hi. The plate projects andhas its projecting end formed with a passage or hole 46 for the boltwhich lines up with the sleeve 48 which latter constitutes a socketmember. Thus, in both keeper constructions a socket member is a commoncharacteristic.

Reference is now had to the third form or adaptation of the invention.This form of the invention is closely allied with that revealed inFigure 4. As a matter of fact, the two figures are practically the sameexcept that in Figure 5 the fixture 40a instead of being in the form ofa flat plate 42 is an L-shaped plate. The plate portion is denoted herein this figure with the numeral 42 and the laterally bent end portion isrounded and denoted by the numeral 420.. Otherwise, the fixture orbracket is the same in that it includes a hole for the bolt 46 and aline-up sleeve 48 which registers with the hole. By reason of thisL-shaped fixture the latter may be placed in a mortice or grooveprovided in the bottom rail of the window sash and screwed or otherwiseanchored therein.

In practice, the nut forming and anchoring bracket 24 is screwed intoplace at about the position shown and this locates the bolt wherewanted. The rail of the sash i0 is mortised and the keeper socket member12 is fitted into plate. With the bolt and socket member properly linedup the detent I8 may then be projected into the socket member forlocking the sash 8 with the sash [0 in an obvious manner. Theintervening relatively shiftable bracket 32 is primarily a sta- '4bilizing brace. By having the brace the over-all fastener is thought tobe not only more rigid but virtually jimmy-proof.

It is thought that persons skilled in the art to which the inventionrelates will be able to obtain a clear understanding of the inventionafter considering the description in connection with the drawings.Therefore, a more length description is regarded as unnecessary.

Minor changes in the shape, size, materials and arrangement of parts maybe resorted to in actual practice without departing from the spirit andscope of the invention, as claimed.

Having described the invention, what is claimed as new is:

1. A sash fastener comprising a bracket having a base provided with adepending wood screw, an upright rising from said base, said uprightbeing polygonal in cross-section and provided with a screw-threaded bolthole, a bolt screwed through said hole and having a finger-grip to oneend, having a smooth detent at the opposite end and a stop flangeadjacent said detent, and a second relatively movable bracket having abase adapted to rest slidably on a portion of a cooperating sash framemember and also having an upright rising from said base, said uprightbeing of a height conformable with the height of the first named uprightand having a smooth-walled bolt hole therein, that portion of the boltbetween said stop flange and first named upright extending freely andslidably through said smooth-walled hole.

2. The structure specified in claim 1 in conjunction with a plate havinga. portion attachable to a sash, said plate also having a fiat portionadapted to assume a position in spaced parallelism in respect to saidrespective uprights and provided with a bolt opening for reception ofsaid detent and a sleeve aligned with said opening and providing asocket into which said detent projects and is accommodated and held.

3. The structure specified in claim 2, wherein that plate portion iswholly flat.

4. The structure specified in claim 2, wherein said plate portion issubstantially L-shaped in edge elevation.
